'93 850 GLT N/A Turbo-able? 850 1993

posted by  someone claiming to be SeanD on  Mon Aug 19 07:25 CST 2002 [RELATED]

I recently bought a '93 850 GLT sedan. It's got 97k on the clock and appears to be in very good shape. I would have really preferred to get a turbo to begin with, but couldn't find one in the area. Does anyone have any thoughts/advice as to converting a N/A engine to a turbo? Should I find a c70 or 850 turbo at a salvage yard and pull off the turbo, or should I look for a non-volvo turbo? Also, what exactly is it going to take to install it? Obviously some ductwork, an oil send and return, but will I have to do a new exhaust and/or ECU? I appreciate any advice anyone has.

    Well....yeah. If you've got enough money. 850 1993

    The 1993 only came N/A, but you can turbo anything, given enough money. The basics involved:
      MAF sensor
      ECU
      Turbo (cartridge)
      Turbo housing (where the impeller sits)
      Downpipe...and probably the cat, too
      Intercooler
      Oil cooler
      Compression-side ducting to intercooler and manifold

    and probably:
      intake manifold
      oil pan

    finally, the T-5 and R engines have:
      sodium-filled valves
      lined cylinder walls
      oil pump with piston spray
      different crank arms and bearings
      crown-forged pistons

    The cost would be enormous. It would probably be cheaper to drop in an entire engine and trans from a turbo 850 / 70. Or better yet, buy a T-5 or R and get the suspension, too!

    '93 850 GLT N/A Turbo-able? 850 1993

    This question comes up on occasion and the general concensus is it is
    cheaper to sell your car and buy a turbo then convert.

    Major modifications for the turbo engine include thicker cylinder
    walls (displaces 2.3L) to handle the heat; sodium filled exhaust valves
    ($50 each and you need 10); forged pistons; 8.5:1 (vs 9.5:1) compression
    ratio; oil cooling spray aimed at piston bottoms; numerous check valves; different exhaust manifold; air-to-air intercooler; larger radiator; heat shields; engine oil cooler. You would really need to swap the whole engine,
    electronics and cooling system.

    There may be additional issues with a 93 that are not well known since
    Volvo did not build a turbo engine for model year 93 (an example
    woould be no turbo ECU available for that year).
